WebSo from this frame the particle's new velocity ( v 1 →) should be r → ∗ ω → where r → is the position of the particle with respect to the centre. So from this frame the particle's kinetic energy will be. 1 2 I ω 2 = 1 2 m r 2 ( v 1 r) 2 = 1 2 m v 1 2. So as you can see the Kinetic energy is different for both the frames. WebIt follows immediately that the kinetic energy , that is, the Kinetic Energy = − 1/2 (Potential Energy) so the total energy in a circular orbit is half the potential energy . The satellite’s motion can be visualized as circling around trapped in the circular potential “well” pictured above. How fast does move?
